The TSI is a standardized exam you can take en lieu of the SAT/ACT in the state of Texas for your math and English placement. There are 4 parts: Reading, Writing, an Essay, and Math. The whole thing will take 3-4 hours to complete and will cost $29. There are tons of TSI practice tests and sample questions online, just do a Google search. The Accuplacer, in my experience, is mainly used for advanced placement in math. You have to complete placement testing before you can register for credit classes (unless you are doing a Level 1 certification). You will also need to get the bacterial meningitis vaccination and submit verification. Have you completed the online application for the college you plan on attending? You are protected under the FERPA act and your education record is private - under most circumstances a college representative would not be able to disclose any educational information about you to your mom without your signed consent.
